Book Description
Advances in Physiological Sciences, Volume 27: Factors Influencing Adrenergic Mechanisms in the Heart is a collection of papers presented at the 1980 satellite symposium of the 28th International Congress of Physiological Science, held in Visegrád, Hungary. This symposium covered the achievements that modify the traditional views of adrenergic regulation of cardiac muscle and coronary blood vessels. This volume is composed 18 chapters and begins with a discussion of the effect of adrenaline on some aspects of electrical and mechanical activity in the frog heart. The subsequent chapters describe the heart rate changes in neurogenic hypertension, the developmental changes of the catecholamine-induced chronotropic responses related to the blood pressure responses, and the inverse reciprocal regulation of cardiac post-synaptic a- and b-adreneceptors by thyroid hormones. Other chapters deal with the mechanism of adenosine-induced inhibition of adrenergic neurotransmission in the ventricular myocardium; the comparative morphological studies of localized exogenous adenosine in heart muscle; adenosine sensitivity of canine coronaries; and the significance of nickel ion in the coronary vascular tone regulation. These chapters are followed by discussions of the physiological and pathological effects of beta modulator release and the histological study of experimental diabetic angiopathy. The last chapters examine some aspects of myocardial noradrenaline metabolism in the ischemic heart and the activity of alpha-adrenoceptor without employing beta blocking agents.

Book Description
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book Description
Advances in Physiological Sciences, Volume 29: Gastrointestinal Defence Mechanisms is a collection of papers that details the findings of research studies on the theoretical and practical aspects of the gastrointestinal defense mechanisms. The title first covers circulation and mucosal defense, and then proceeds to tackling the association of gastrointestinal mechanisms with the secretory functions. Next, the selection deals with the resistance in gastric mucosa and mucosal energy provision. The text also discusses cell renewal and toxicity, along with biotransformation and nutrition. In Part VII, the title details the immunomechanisms of defense at mucosa. The last part covers the second line defense at liver and enterohepatic circulation. The book will of great interest to both researchers and practitioners of medical fields concerned with the digestive system.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
